+#### Crypto in str0m
+
+##### What cryptographic provider does str0m use?
+- On non-Windows platforms, str0m uses OpenSSL as the primary cryptographic provider.
+- On Windows, you can choose between:
+  - wincrypto: Uses Windows Crypto API (CNG).
+  - openssl: Uses OpenSSL as the cryptographic backend.
+
+##### What are the build options for OpenSSL?
+When using OpenSSL, there are two alternatives:
+- Vendored: Downloads and builds OpenSSL from source. This ensures compatibility and avoids
+dependency on system-provided OpenSSL.
+- Non-vendored: Relies on the OpenSSL library provided by the system.
+
+##### What's the recommended build configuration?
+For the easiest build experience:
+- On Windows: Use wincrypto.
+- On Non-Windows Platforms: Use openssl and vendored.
+
+##### Does str0m support a pure Rust DTLS implementation?
+Currently, str0m does not include a pure Rust implementation of DTLS. It relies on external
+cryptographic libraries like OpenSSL for DTLS functionality.
+
+##### Can I contribute a DTLS implementation?
+Yes! Contributions for a DTLS 1.2 implementation are welcome, but note:
+- It should be synchronous.
+- It should be implemented entirely in pure Rust.
+If you're interested in contributing, feel free to discuss with the str0m maintainers before starting.
